Grounded Copeland Hermetic New Install

[Slatts]

No man, Ryan thinks I had a single phase and connected it to a 3 phase, don't you see about the configuration? Slatts is a kool dude

Stop it royal, you've made me blush.

[Slatts]

Maybe the terminology is different between here and Australia. A single "leg" won't cause any harm. The second leg is the 208/230 "single phase" which will kill a 3 phase compressor.

Here we switch all 3 phases.

If we loose 1 through a burnt contact, wire or fuse, the compressor is said to be 2 phasing.

occasionally I've seen 3 phase compressor where only 2 phases are switched, particularly in old York airconditioning condensing units.

We reticulate at 240Vto earth, 415V between phases at 50 Hz.

Dude, if you around Boston, I know some mean dudes I ride with and I mean Harley! Terminology doesn't change, leg or phase, same thing, we are all working on the the same thing, cooling our customers and being profitable doing so, tx guys.

kind of counter intuitive, don't you think?

I have $12

That'll get ya a sixpack of german beer on a windy day.

Do you have single phase 208/230 motors?

Who want's German Beer? American whiskey any day

[2sac]

What time is it there? lol

[Slatts]

Do you have single phase 208/230 motors?

Yes, all of our single phase motors are 240 volt single phase.

[Slatts]

Oh, and it's 14:47, 9/12/12 (D/MM/YY)

[2sac]

Yes, all of our single phase motors are 240 volt single phase.

So, a single phase motor has 2 legs of power I assume?

[Slatts]

1 active and a neutral tied to earth potential.

[2sac]

You're bringing in a single 240 and a ground, not 120/120?

[Slatts]

We also have 415 volt single phase motors that use 2 phases.

If you follow me.

They're something of a rarity though. Kirby tend to use them on their 3 phase condensing units so you don't need to run a neutral to it when installing it.

A bit of a trap for young players.

[Slatts]

You're bringing in a single 240 and a ground, not 120/120?

yes.

240 volt, a neutral and a separate ground.

[Slatts]

We don't use 120 here except for on control circuits in machines from over your way.

[2sac]

At least I know I'm not crazy now. LOL

[Slatts]

why? have you been professionally evaluated?
